[GreenKeys] Selective Fading Experiment

[Jeff G]

At the ship, we have at least one 16ch multiplexer that still seems to be
intact enough that it might do something. I'd have to go back through my
pics to see what the ID on it is, but it has 16 "cards" each with
adjustable m/s freq.

Found it - this guy: https://www.navy-radio.com/rtty-mux-ucc1.htm
